Abstract

L'invention concerne un système et un procédé DMT (à multitonalité discrète) capable d'adapter en continu le débit binaire du système en ligne. Ce système DMT permet d'obtenir un protocole robuste et rapide permettant d'effectuer cette adaptation de débit sans coupure. Ce système DMT permet également d'obtenir un procédé de verrouillage et de codage à surdébit réduit par rapport aux systèmes DMT conventionnels. Ce système et ce procédé DMT permettent d'obtenir une adaptation de débit sans coupure avec différents niveaux de puissance. Ce procédé de verrouillage et de codage permet d'obtenir un système présentant une capacité d'adaptation de débit sans coupure. Ce système et ce procédé peuvent être mis en oeuvre sous forme de matériel ou, dans une variante, sous forme d'une combinaison de matériel et de logiciel.
